Description

Ventil, insbesondere Druckreduzierventil Valve, especially pressure reducing valve
Die gegenständliche Erfindung betrifft ein Ventil, insbesondere ein Druckreduzierventil, mit einem Gehäuse, welches mit einem zylindrischen Hohlraum für einen Rotor, mit einem Zuflußkanal für ein unter Druck stehendes Medium und mit einem Abflußkkanal für das mit vermindertem Druck abströmende Medium ausgebildet ist.The subject invention relates to a valve, in particular a pressure reducing valve, with a housing which is formed with a cylindrical cavity for a rotor, with an inflow channel for a medium under pressure and with an outflow channel for the medium flowing off under reduced pressure.
Bei einer Vielzahl von technischen Anlagen ist es erforderlich, den Druck von unter hohem Druck stehenden Medien, wie Flüssigkeiten oder Gasen, herabzusetzen. Dies trifft z.B. beim Transport von Gasen zu, welche unter hohem Druck über großen Entfernungen gefördert werden. Ebenso gilt dies für Wasserversorgungsanlagen, in welchen deshalb, da die Wasserversorgung auch bei hoch gelegenen Abnehmern gewährleistet sein muß, das Wasser unter hohem Druck steht. Bei der Abgabe dieser Medien an Verbraucher muß jedoch der bestehende Druck auf einen den Erfordernissen entsprechenden Druck herabgesetzt werden. Um dieser Bedingung zu entsprechen, werden in derartigen Anlagen Ventile, insbesondere Druckreduzierventile, durch welche die Medien hindurchgeleitet werden, angeordnet. Weitere Anwendungsbereiche sind jegliche technische Anlagen, in welchen sich ein unter hohem Druck stehendes gasförmiges oder flüssiges Medium befindet, dessen Druck herabgesetzt werden muß, wie Kälteanlagen, Druckluftversorgungsanlagen und hydraulische Anlagen.In a large number of technical systems, it is necessary to reduce the pressure of media under high pressure, such as liquids or gases. This applies e.g. when transporting gases which are conveyed under high pressure over long distances. This also applies to water supply systems, in which the water is under high pressure because the water supply must also be guaranteed for high-altitude customers. When supplying these media to consumers, however, the existing pressure must be reduced to a pressure that meets the requirements. In order to meet this condition, valves, in particular pressure reducing valves, through which the media are passed, are arranged in such systems. Further areas of application are any technical systems in which there is a high-pressure gaseous or liquid medium, the pressure of which has to be reduced, such as refrigeration systems, compressed air supply systems and hydraulic systems.
Bei den bisher bekannten Anlagen, in welchen eine Druckreduzierung bewirkt wird, bedeutet dies jedoch, daß hierdurch die im Medium enthaltene Druckenergie insbesondere in Wärme umgesetzt wird, welche nicht genützt wird, weswegen sie verloren geht. Der gegenständlichen Erfindung liegt somit die Aufgabe zugrunde, ein Ventil zu schaffen, durch welches die in Medien enthaltene Druckenergie in kinetische Energie und gegebenenfalls in elektrische Energie umgesetzt werden kann.In the previously known systems in which a pressure reduction is effected, however, this means that the pressure energy contained in the medium is thereby converted into heat in particular, which is not used, which is why it is lost. The object of the invention is therefore to create a valve by means of which the pressure energy contained in media can be converted into kinetic energy and, if appropriate, into electrical energy.
Es sind seit vielen Jahren Turbinen bekannt, deren Rotoren mittels strömender Medien, insbesondere mittels Wasser, in Rotation gesetzt werden, wodurch kinetische Energie und mittels Elektrogeneratoren elektrische Energie erzeugt werden kann. Bekannte Turbinen sind jedoch deshalb nicht als Sperrventile verwendbar, da durch diese keine Absperrung des unter Druck stehenden Mediums bewirkt werden kann. Der Grund hierfür liegt darin, daß bekannte Turbinen aus Metall hergestellt sind, wodurch aufgrund der Wärmedehnungen keine solche Paßgenauigkeit des Rotors im Gehäuse erzielbar ist, daß sie auch als Sperrventil wirken können.Turbines have been known for many years, the rotors of which are set in rotation by means of flowing media, in particular by means of water, whereby kinetic energy and electrical energy can be generated by means of electrical generators. Known turbines, however, cannot be used as check valves because they cannot shut off the pressurized medium. The reason for this is that known turbines are made of metal, which means that due to the thermal expansion, such a precise fit of the rotor in the housing cannot be achieved that they can also act as a check valve.
Der gegenständlichen Erfindung liegt somit die Aufgabe zugrunde, ein Ventil mit einem in einem zylindrischen Hohlraum angeordneten Rotor zu schaffen, durch welche sowohl die Funktion eines Sperrventils als auch die Funktion eines Druckreduzierventils erfüllt wird, wobei die bei der Funktion eines Druckreduzierventiles anfallende Energie gewonnen werden kann. Dies wird erfindungsgemäß dadurch erzielt, daß das Gehäuse und der Rotor aus einem keramischen Material hergestellt sind und daß der Rotor als zylindrischer Körper ausgebildet ist, welcher an seiner Mantelfläche mit einer Vielzahl von in Drehrichtung im Abstand voneinander befindlichen Ausnehmungen ausgebildet ist, wobei die zwischen den Ausnehmungen befindlichen Bereiche der Mantelfläche an die Innenfläche des im Gehäuse befindlichen Hohlraumes und die Stirnflächen des Rotors an die Stirnflächen des Gehäuses abdichtend anliegen.The object of the present invention is therefore to provide a valve with a rotor arranged in a cylindrical cavity, by means of which both the function of a shut-off valve and the function of a pressure reducing valve are fulfilled, and the energy generated in the function of a pressure reducing valve can be obtained , This is achieved according to the invention in that the housing and the rotor are made of a ceramic material and that the rotor is designed as a cylindrical body which is formed on its outer surface with a plurality of recesses which are spaced apart in the direction of rotation, the between the Recess areas of the lateral surface sealingly abut the inner surface of the cavity located in the housing and the end faces of the rotor on the end faces of the housing.
Da keramisches Material keinen maßgeblichen Wärmespannungen unterliegt, können sowohl der Rotor als auch das Gehäuse mit sehr hoher Paßgenauigkeit hergestellt werden, wodurch durch dieses Ventil bei einem Blockieren der Welle des Rotors die Funktion eines Sperrventiles erfüllt werden kann. Sobald demgegenüber die Welle des Rotors freigegeben wird, wobei die Rotationsgeschwindigkeit der Welle elektronisch geregelt werden kann, erfüllt dieses Ventil die Funktion eines Reduzier ventiles. Die über die Welle des Rotors übertragene elektrische Energie kann in weiterer Folge gewonnen werden, wobei insbesondere ein Elektrogenerator betrieben werden kann. Die durch den Elektrogenerator gewonnene Energie kann in einem Akkumulator gespeichert werden. Sie kann jedoch auch in Heizenergie umgewandelt werden, welche z.B. in einen thermischen Speicher eingespeist wird.Since ceramic material is not subject to significant thermal stresses, both the rotor and the housing can be manufactured with a very high degree of accuracy, which means that this valve can function as a check valve when the shaft of the rotor is blocked. In contrast, as soon as the shaft of the rotor is released, whereby the rotational speed of the shaft can be electronically controlled, this valve fulfills the function of a reducing valve. The electrical energy transmitted via the shaft of the rotor can subsequently be obtained, in particular an electrical generator being able to be operated. The energy generated by the electrical generator can be stored in an accumulator. However, it can also be converted into heating energy, which e.g. is fed into a thermal store.
Vorzugsweise sind die im Rotor befindlichen Ausnehmungen als radial ausgerichtete Nuten ausgebildet. Nach einer bevorzugten Ausführungsform sind die Ausnehmungen mit seitlichen Wangen ausgebildet, sodaß sie nur nach radial außen offen sind. Weiters sind vorzugsweise der Zuströmkanal und der Abströmkanal zueinander angenähert diametral angeordnet. Zudem kann der Rotor mit einer zentralen Ausnehmung ausgebildet sein, in welche eine aus elastischem Material hergestellte Muffe eingesetzt ist.The recesses in the rotor are preferably designed as radially aligned grooves. According to a preferred embodiment, the Recesses formed with side cheeks, so that they are only open radially outwards. Furthermore, the inflow channel and the outflow channel are preferably arranged approximately diametrically to one another. In addition, the rotor can be formed with a central recess into which a sleeve made of elastic material is inserted.
Nach einer bevorzugten Ausführungsform ist das Gehäuse als zweiteiliger, insbesondere quadrischer Körper ausgebildet, wobei der eine Teil mit dem Hohlraum und dem Zuströmkanal sowie dem Abströmkanal ausgebildet ist und der andere Teil als Abdeckplatte ausgebildet ist.According to a preferred embodiment, the housing is designed as a two-part, in particular quadratic body, one part being designed with the cavity and the inflow channel and the outflow channel, and the other part being designed as a cover plate.

Das in den Fig.l bis 3 dargestellte Ventil besteht aus einem Gehäuse 1 , welches mit einem angenähert zylindrischen Hohlraum 1 1 , einem Zuströmkanal 12 und mit einem Abströmkanal 13 ausgebildet ist und welches mittels einer Abdeckung 15 verschließbar ist.The valve shown in Fig.l to 3 consists of a housing 1, which is formed with an approximately cylindrical cavity 1 1, an inflow channel 12 and an outflow channel 13 and which can be closed by a cover 15.
In den zylindrischen Hohlraum 1 1 ist unter Zwischenlage von zwei Dichtungsscheiben 14 ein zylindrischer Rotor 2 eingesetzt, welcher an seiner Mantelfläche mit einer Vielzahl von radial ausgerichteten, schlitzartigen Hohlräumen 21 ausgebildet ist. Zur Aufnahme der Dichtungsringe 14 ist der Rotor 2 an seinen beiden Stirnflächen mit zylindrischen Ausnehmungen 24 versehen. In eine zentrische Bohrung 23 des Rotors 2 ist eine Kupplungshülse 3 eingesetzt, welche an ihrer radial inneren Seite mit Nuten bzw. Keilen zur Kupplung mit einer Welle ausgebildet ist. Diese Welle durchsetzt das Gehäuse 1 in einer Bohrung 10 und die Abdeckung 15 in einer Bohrung 20.A cylindrical rotor 2 is inserted into the cylindrical cavity 11 with the interposition of two sealing disks 14 and is formed on its outer surface with a large number of radially oriented, slot-like cavities 21. To accommodate the sealing rings 14, the rotor 2 is on its provided both end faces with cylindrical recesses 24. In a central bore 23 of the rotor 2, a coupling sleeve 3 is inserted, which is formed on its radially inner side with grooves or wedges for coupling with a shaft. This shaft passes through the housing 1 in a bore 10 and the cover 15 in a bore 20.
Sowohl das Gehäuse 1 und die Abdeckung 15 als auch der Rotor 2 sind aus einem keramischen Material hergestellt. Da ein keramisches Material keinen maßgebliche Wärmedehnungen unterliegt, können die Ausnehmungen 1 1 und der Rotor 2 mit so hoher Paßgenauigkeit hergestellt werden, daß zwischen diesen beiden Bauteilen kein Medium hindurchströmen kann. Da demgegenüber die Kupplungshülse 3 aus einem elastischen Material hergestellt ist, werden auf die Welle wirkende Stellkräfte durch die Kupplungshülse 3 aufgenommen, sodaß sie auf den Rotor 2 nicht zur Wirkung kommen bzw. dieser im Hohlraum 1 1 schwimmend gelagert ist.Both the housing 1 and the cover 15 and the rotor 2 are made of a ceramic material. Since a ceramic material is not subject to significant thermal expansion, the recesses 1 1 and the rotor 2 can be manufactured with such a high degree of accuracy that no medium can flow between these two components. In contrast, since the coupling sleeve 3 is made of an elastic material, actuating forces acting on the shaft are absorbed by the coupling sleeve 3, so that they do not act on the rotor 2 or the latter is floatingly supported in the cavity 11.
Das in den Fig.4 bis 6 dargestellt zweite Ausführungsbeispiel unterscheidet sich vom ersten Ausführungsbeispiel dadurch, daß die Ausnehmungen 21a des Rotors 2a durch seitliche Wangen 22 abgeschlossen sind, wodurch die Ausnehmungen 21a nur nach radial außen offen sind.The second exemplary embodiment shown in FIGS. 4 to 6 differs from the first exemplary embodiment in that the recesses 21a of the rotor 2a are closed off by lateral cheeks 22, as a result of which the recesses 21a are only open radially to the outside.
Im Betrieb dieser Einrichtung wird der Kanal 12 des Gehäuses 1 an eine Leitung, in welcher sich unter Druck stehendes Medium befindet, angeschlossen. Solange der Rotor 2 blockiert ist, erfüllt diese Einrichtung die Funktion eines Absperrventiles. Sobald jedoch Medium mit vermindertem Druck über den Abströmkanal 13 in eine Verbraucherleitung abströmen soll, wird der Rotor 2, 2a freigegeben, wodurch das Medium an den Flanken derjenigen Nuten 21 , 21a, welche sich im Zuströmkanal 12 befinden, zur Wirkung kommt, wodurch der Rotor 2, 2a in Drehung versetzt wird. Das in den Nuten 21 , 21a befindliche Medium gelangt hierdurch mit vermindertem Druck in den Abströmkanal 13. Die durch den Rotor 2, 2a erzeugte Rotationsenergie wird über die mit dem Rotor 2, 2a gekuppelte Welle übertragen, wodurch sie gewonnen werden kann. Vorzugsweise wird mittels der Welle ein Elektrogenerator angetrieben, wobei die durch diesen erzeugte elektrische Energie entweder in einem Akkumulator gespeichert werden oder in Heizenergie, welche in einem thermischen System gespeichert wird, umgewandelt werden kann. Da durch dieses Ventil sowohl die Funktion eines Absperrventils als auch die Funktion eines Reduzierventils erfüllt wird, kann sie in einer Vielzahl von technischen Anlagen eingesetzt werden, um Energie, welche bisher verloren geht, zu gewinnen und zu nützen. Die Steuerung der Verdrehung des Rotors 2 und damit die Steuerung des Reduzierventils erfolgt über eine auf den Elektrogenerator wirkende elektrische Schaltung.In the operation of this device, the channel 12 of the housing 1 is connected to a line in which the medium under pressure is located. As long as the rotor 2 is blocked, this device fulfills the function of a shut-off valve. However, as soon as medium with reduced pressure is to flow into a consumer line via the outflow channel 13, the rotor 2, 2a is released, as a result of which the medium acts on the flanks of those grooves 21, 21a which are located in the inflow channel 12, as a result of which the rotor 2, 2a is rotated. The medium located in the grooves 21, 21a thereby reaches the outflow channel 13 with reduced pressure. The rotational energy generated by the rotor 2, 2a is transmitted via the shaft coupled to the rotor 2, 2a, whereby it can be obtained. An electric generator is preferably driven by means of the shaft, it being possible for the electrical energy generated by it to either be stored in an accumulator or to be converted into heating energy which is stored in a thermal system. Since this valve fulfills both the function of a shut-off valve and the function of a reducing valve, it can be used in a large number of technical systems in order to obtain and use energy that has previously been lost. The control of the rotation of the rotor 2 and thus the control of the reducing valve takes place via an electrical circuit acting on the electrical generator.
Wie dies weiters in Fig.7 dargestellt ist, kann der Rotor aus zwei angenähert symmetrischen Teilen 2b und 2c bestehen, wobei der Teil 2b mit Bohrungen 25 und der Teil 2c mit diesem zugeordneten Zapfen 26 ausgebildet ist, durch welche sie miteinander verbindbar sind. Hierdurch wird eine Vereinfachung in der Herstellung dieser Bauteile erzielt. Es ist dabei zu berücksichtigen, daß Bauteile aus keramischem Material nur durch Pressung herstellbar sind.As is also shown in FIG. 7, the rotor can consist of two approximately symmetrical parts 2b and 2c, part 2b being formed with bores 25 and part 2c with pins 26 associated therewith, by means of which they can be connected to one another. This simplifies the manufacture of these components. It must be taken into account that components made of ceramic material can only be manufactured by pressing.
Wie weiters aus den Fig.8 und 9 ersichtlich ist, kann das Gehäuse längs der Linie A-B in zwei angenähert quaderförmige Bauteile la und lb unterteilt sein, welche mit jeweils einer teilzylindrischen Ausnehmung ausgebildet sind. Diese beiden Bauteile la und lb sind mit Bohrungen 16 ausgebildet, in welche Spannbolzen einsetzbar sind. Weiters sind die beiden Bauteile la und lb mit Ausnehmungen zur Ausbildung des Zuströmkanals 12 und des Abströmkanals 13 ausgebildet.As can also be seen from FIGS. 8 and 9, the housing can be divided along the line A-B into two approximately cuboid components la and lb, each of which is formed with a partially cylindrical recess. These two components la and lb are formed with bores 16 into which clamping bolts can be inserted. Furthermore, the two components la and lb are formed with recesses to form the inflow channel 12 and the outflow channel 13.
Bei dieser Ausbildung kann der Rotor in die teilzylindrischen Ausnehmungen eingesetzt werden, welche hierauf mittels der in die Bohrungen 16 eingesetzten Spanbolzen miteinander verbunden werden. In this configuration, the rotor can be inserted into the partially cylindrical recesses, which are then connected to one another by means of the clamping bolts inserted into the bores 16.
